'WICK-CARRIER.

Specification of Letters Patent.

Patented Nov. t9, 1918.

To all tf1/tom t may concern:

Be it known that we, FREDERICK W. SPANGLER and Con'rLAND W. DAVIS, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Wick-Carriers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the Same.

One reason for unsuccessful results in the illumination produced by incandescent mantle lamps of the blue lame wick type may be attributed to the improper positioning of the wick Within its burner. Realizing the importance of the proper mounting of the wick, it has been proposed to supply a wick carrier with each wick to be dispensed to the customer, wherein the wick has been properly adjusted in its carrier and is ready to be inserted in the burner.

The wick carrier should be so formed that the consumer may readily insert it into a burner so that the new wick will occupy the same relative position for burning as the old one. By a careful and accurate adjustment of the wick and carrier, by skilled workmanship, the consumer may be supplied with a combined wick and carrier which will function properly within` the burner and give the maximum eiiiciency with relatively little labor and trouble on the part of the consumer in the replacement of the wick.

The object of this invention is to supply a wick and carrier for the trade which has been mounted by skilled labor, wherein the consumer is relieved from the trouble and care incident to replacements, thereby increasing the efliciency and utility of a burner and eliminating the undesirable results heretofore experienced by the hap-hazard mounting of the wick within its carrier, by inexperienced persons. The Wick being insert-ed in its carrier by skilled labor may be uniformly positioned in the burner and is presented to the consumer preliminarily charred so that the carrier may be attached to a part of the burner mechanism by the consumer to secure the same results from the new wick as were obtained in the use of the consumed wick.

To insure the proper adjustment of the Wick and carrier within a burner, and to secure efliciency in the operation of the lamp, the wick carrier has been supplied with a rack secured thereto for thepurpose of moving the wick carrier within the burner. In this construction, the provision of the rack renders the article expensive, and in the interest of economy it is proposed to supply to the consumer a wick properly mounted within its carrier andhaving means to be engaged by a detached wick raising rack. In burners wherein the inner tube is supported from the outer tube, the wick carrier may be slotted or bifurcated to span these supports, and these supports may operate to guide the wick in its vertical movement. The supports of the inner tube also serve to limit the vertical movement of the wick by engaging a part of the wick carrier or a part of its elevating mechanism. 'Ihe' elongated slots provided in the wick carrier for its movement with relation to the supports of the innertube may be closed by means carried by the elevating rack. By so mounting the wick carrier with relation to the tube supports, rotary movement of the wick and carrier is prevented, and also the amount of vertical travel of the wick is limited. rIhe proper mounting of the wick within the carrier will insure its most useful and economical burning position, and the carrier coperating with the burner parts prevents the use of the` wick when the same has passed \its useful length.

Q A practical form of the invention is illustrated in the accompanying drawings, but it is to be understood that the construction therein shown is for the purpose of illustration only, and not as defining the limits of the invention.

In the drawings Figure 1 is a front elevation disclosing a wick mounted in its carrier and a rack secured to a part of the carrier.

Fig. 2 is a detail, sectional view disclosing a part of a burner wherein inner tube supports are positioned in the wick passage.

Fig. 3 is a vertical, sectional view through the structure of Fig. l and at right angles thereto.

Fig. 4L is a front elevation of the wick carrier.

j Fig. 5 is a rear elevation of a burner rack adapted to cooperate with the wick carrier.

Fig. 6 is a side elevation of the burner rack.

A Fig. 7 is a plan view of the rack.

Fig. 8 is a horizontal, sectional view through the wick disclosing the means to secure the wick to the wick carrier.

Referring more particularly to the embodiment of the invention set forth in the accompanying drawings,I the wick`V asl indi A cated at 1, is shown bifurcated at 2 for the lower end of the wick. In using the wick in a burner wherein the inner wick tube such as 3 in Fig. 2 is spaced from the outer wick tube 4 by a vane 5, the wick may straddle the vane in its vertical movement in the burner by means of its bifurcation, indicated at 2. The upper end of the wick is preferably circular in form as indicated at 6 in Fig. 8.

The wick carrier may be of any suitable material and may -be formed of metal as indicated at 7 and is shown provided with a plurality of perforations 8 which serve to lighten the structure and at the same time prevent conduction of heat to the fuel in the reservoir. The wick carrier 7 may be provided with any suitable means to engage the wick, one form of engaging means being shown as the prongs 9positioned at the upper and lower edges of the wick carrier.

The wick carrier is preferably provided with an elongated slot 110 which extends from the lower edge 11 of the wick carrier .to a point 12 near the upper end of the wick carrier. The walls forming the lower part of the slot 10 are preferably contracted at 13 to thereby form a narrower slot 14 at the lower portion of the wick carrier. The carrier maybe provided with a plurality of the slots 10 arranged'opposit'e to each other as shown in Fig. 3 to coperate with a plurality of vanes 5 carried by the burner.-v The open end of one of the slots 10 may be closed by means carried by a. detachable burner rack indicated at 15.

The lower part of the wick carrier is shown provided with a plurality of lugs' 16y which are'shown formed by angular or bayonet slots 17 positioned adjacent the contracted end 14 of the slot 10.

The lower part of the rack 15 is shown provided with a plate 18, which may be formed with oppositely positioned ears 19 at the upper edge thereof. rThe plate 18 is preferably offset from the rack 15 as illustrated in Fig. 6 whereby the rack when attached tothe wick carrier may be positioned parallel to the wick carrier for contact with suitable elevating mechanism carried by the burner. The plate 18 is shown arcuate in form to conform to the configuration of the wick carrier, and the ears 19 are shown arcuate to engage the curved wick carrier.

In applying the rack to the wick carrier, the lower end of the wick carrier is con- .When the wick carrier and its wick have been properly mounted within the burner, and the vane 5 passed within the slot 10,

l the end` 12 of the slot 10 will serve to `limit the downward movement of the wick with- 1n the lamp by theengagement of the wick carrier with the upper edge of the vane 5,

and the plate 18 will prevent undue elevation of the wick within the lamp by its engagement with the lower edge of the vane 5. This arrangement will serve to preclude the use of a wick beyond its predetermined burning capacity, and the vanes` of the.

burner will Aserve to guide the wick in its vertical travel within the burner and prevent rotary movement of the vcarrier with relation to the wick tube.

By the construction herein illustrated and described, the consumer maybe supplied with a wick properly mounted within its carrier to be attached to a wick raising rack which may be furnished as a part ofthe lamp burner, thus reducing the cost of supplying a mounted wick to the consumeras well as reducing'the labor on the part oit the consumer as compared with rewicking an old burner with a mounted wick.

1t is obvious thatv various changes may bemade in the form and,` proportion of parts, and the right is reservedto make such changes and alterations in the wick carrier and its detachable rack as may fairly fall withm the scope of the appended claims.

Having thus described our invention, what i 2.
